Solar PV Analysis of Ballarat, Australia
The location of Ballarat, Victoria, Australia is fairly good for year-round energy generation using solar photovoltaic (PV) systems. During summer and spring, you can expect a high amount of energy production due to longer daylight hours and more direct sunlight. Specifically, in summer you can expect about 7.85 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar panels and in spring, about 5.78 kWh/day per kW.
During autumn and winter, the energy production will decrease due to shorter daylight hours and less direct sunlight. In autumn you can expect about 3.96 kWh/day per kW of installed solar panels while in winter this drops to around 2.51 kWh/day per kW.
To get the most out of your solar PV system year-round at this location, it's recommended that your panels are installed at an angle tilted 32 degrees towards the North. This position will allow them to capture as much sunlight as possible throughout the different seasons.
As for potential impediments to solar production in Ballarat, Victoria, there could be several factors such as weather conditions or physical landscape features which may affect efficiency.
Ballarat is known for its variable weather conditions including frequent cloud cover which could reduce the amount of sunlight reaching your panels hence reducing their output. Also being located within a region with hilly topography might mean that some locations may not be suitable if they are shaded by hills or trees during parts of the day.
One way to mitigate these issues would be careful site selection when installing your solar PV system - choose a spot with minimal shading throughout the day and year if possible.
Another factor could be dust or bird droppings on the surface of your panels which can reduce their efficiency over time - regular cleaning would help maintain their performance levels.
In conclusion, while there are potential challenges related to weather variability and topography in Ballarat that could impact solar energy production, these can be mitigated with careful planning and maintenance. Overall, Ballarat could be a good location for generating solar energy especially during the sunnier parts of the year.
Note: The Southern Temperate Zone extends from -35° latitude South down to -66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 501 locations across Australia. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Ballarat
Seasonal solar PV output for Latitude: -37.5621587, Longitude: 143.8502556 (Ballarat, Australia), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 32° North in Ballarat, Australia
To maximize your solar PV system's energy output in Ballarat, Australia (Lat/Long -37.5621587, 143.8502556) throughout the year, you should tilt your panels at an angle of 32° North for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Ballarat, Australia
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Ballarat, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° North in Summer | 42° North in Autumn | 52° North in Winter | 30° North in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Ballarat, Australia
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Ballarat, Australia.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Ballarat, Australia
Ballarat, Australia is located in an area characterized by a mix of flat and hilly terrains. It sits at an elevation of approximately 435 meters above sea level. The city is surrounded by highlands to the north, rolling hills to the east and west, and flatter plains towards the south.
When considering large-scale solar PV installations, the best locations are typically flat areas with a high amount of sunlight exposure (insolation) throughout the year. In this case, the flatter plains to the south of Ballarat would be most suitable for large-scale solar PV installations as they would provide ample space for such facilities while also ensuring maximum exposure to sunlight.
However, it's important to note that factors such as local climate conditions (particularly cloud cover), land use restrictions or zoning laws, proximity to electrical grids or substations for power transmission also play crucial roles in determining suitability for solar farms. Therefore a comprehensive feasibility study would be required before confirming any location as appropriate for large-scale solar PV installation.
Australia solar PV Stats as a country
Australia ranks 7th in the world for cumulative solar PV capacity, with 19,076 total MW's of solar PV installed. This means that 10.70% of Australia's total energy as a country comes from solar PV (that's 2nd in the world). Each year Australia is generating 742 Watts from solar PV per capita (Australia ranks 2nd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Australia?
Yes, there are a variety of incentives available in Australia to businesses wanting to install solar energy. These include:
1. Renewable Energy Target (RET): The RET provides businesses with financial assistance for installing and operating renewable energy systems such as solar panels. Businesses may be eligible to receive certificates that can be sold or traded on the open market for additional income.
2. Feed-in Tariffs: Some states offer feed-in tariffs which pay businesses for generating and exporting excess electricity from their solar panel system back into the grid during peak demand periods.
3. Solar Credits: The Solar Credits program provides households and small business owners with an upfront discount when purchasing a new solar system, based on the amount of renewable energy generated by the system over its lifetime.
4. Tax Breaks: Small business owners may be able to claim tax deductions on certain expenses associated with installing a solar power system, including installation costs, maintenance expenses and interest payments related to financing arrangements taken out specifically for this purpose.
